effects the releasing operation desired. A

construction of the above character is shown and described in the patentto Derby No. 1,187 ,15, dated June 13, 1916, for release box, and thepresent invention embodies an improved construction whereby the abovementioned releasing mechanism is rendered ca-. pable of manual 0eration.

An object of thls invention is to provide a releasing mechanism which iscapable of being operated either electrically or manually, theconstruction being such that the elements constituting one operatingmechanism do not interfere with the operation of the. elementsconstituting the other form of operating mechanism.

As a further feature, the mechanism is provided with a resettingmechanism which greatly facilitates this operation, particularly whendone by inexperienced hands.

Further ob'ects will appear as the invention is described more fully inconnection with the accompanying drawings wherein:

Figure 1 is a view in side elevation, partly broken away and in section,showing a preferred form of the invention.

Figure 2 is a view in elevation, taken from the left in Figure 1, andshowing the manual operating mechanism.

Referring to the above drawings, a indicates a housing provided withapertured lugs a for securing the mechanism to a support. A lever 12 ispivoted at b to the outsideof the housing and is maintained in theposition shown in Figure 1 by means of a catch 6 which engages a triggerarm 0' upon pivoted lever 0. Movement of lever a is prevented b theengagement of tooth d with the end t ereof. Tooth d is formed on pivotedlever d and a spring (1 connected between the lever and a pivoted latch0, normally tends to move the tooth out of engagement with the end ofthe lever c. This movement is prevented by latch e which engagestromagnet f is mounted on the housing above the latch e and, whenenergized, serves to release the latch and permit spring (1 to move thelever d to release the lever 0 which, in turn, releases lever b, thuspermitting the fire extinguishing mechanism to be operated. An aperture(1 is formed in one face of the housing a and bracket 9 is mounted overthe aperture to provide a bearing for a lever h. This lever is formedwith an arm k which extends upwardly into a second bracket 71 whichcarries a cable j. The cable 3' may be of any desired length and hassecured at the other end thereof a handle j which is manually operated.If desired, a protective tube 71 is mounted on the bracket to enclosethe cable 1', as shown in Figure 1. i The lever h is held normally inthe position shown in Figure 1 by spring 11 and the force of this springmust be overcome when the device is to be manual- 1y operated. A pull onthe handle 9" is transmitted through cable j and arm k to lever h whichovercomes the force of the spring k and lifts the latch e upwardly. Thisdisengages the lever d, described above, and permits the mechanism to be0 erated.

To effect the resetting o the mechanism, a plunger is is mounted in thehousinga. This plunger is held in a retracted position by spring is andmay be pushed in manually to force lever 0 into operative engagementwith levers d and b. After the lever b is moved to the position shown inFigure 1, plunger is is pushed inwardly to cause the lever c to engagethe levers b and (1, thus resetting the mechanism.

Itwill be seen that the electrical release may be effected in the usualmanner as described in the. above mentioned patent without interferingwith the manual releasing mechanism in the slightest. If it should bedesirable to release the mechanism manually .the cable 7' is pulled, asdescribed above, and

the operation is accomplished' It will be apparent that slight changesmay be made in the design and arrangement of the foregoing elementswithout departing from the scope of the invention as defined in theappended claims. the upper extremlty of the lever d.
